WINDLASS ATTACHMENT FOR T12/ACTORS.

To all whom t lmay concern Be it known that I, XVILLIAM TURNBULL, a citizen of the United States, residing at Peoria, in the county of Peoria and State of Illinoisnhave vinvented new and useful Improvements in Windlass Attachments for Tractors, of .which the following is a specication.

Thisjnvention relates' to windlass attac-h-v ments for tractors and the like for such purposes as grubbing and hauling, and also for pulling' the tractor itself out of diniculties.

The-object is to simplify andimprove the construction and arrangement of such an attachme'nt.l

- y. Briefly, the form of the invention herein lthe transverse shaft by vmeans ofa chain drive, and acontrollable clutch mechanism.

In the accompanying drawings- Fig. l shows a side'elevation of a tractor I provided with an attachment embodying my invention.

Fig. 2 shows a front elevation of the at tachment.

Fig. 3 shows a'plan view, partly in section, of the same applied to the frontend of a tractor frame.

Fig. et shows a side elevation of the attachment, with the cover of the chain drive casing removed.

Fig. 5 shows a side elevation of the attachment in place on a tractor. v

Fig. 6 shows a fragmentary view of the attachment, with the chain'drive casing in section.

Fig. 7 shows a detail, sectionalv view, .taken on the line 77 of Fig. 6.` i f In the drawings a'tractor is shown with a longitudinally extending shaft 10 connected to the front end of a crank-shaftA 11 of the motor by means of a multipleV disk clutch 12,contr0lled by a hand lever 13. The shaft- 10 may replace the usual starting crank and Specification of Letters Patent.

is journalled in bearings 14 on the front cross-bar 15 of the main frame of the tractor. This shaft, at its forward end, con' nects with a transverse shaft 16 by suitable said shaft 16 being journalled in a casing 18 detachably secured to the projecting front endsof the side bars 19 of the main frame.

At-one end of the shaft 16 is a sprocketl 4chain drive 20, running to a windlass 21 journalled below the main frame onbrackets 22 made integral with the casing 18 and also detachably secured to the projecting front ends of the side bars of the main frame. A casing 23, preferably, encloses the chain drive and the arbor 241 of the Normally the clutch 25 is out of driving' engagement while the friction clutch mechanism` 12 remains in driving engagement. Then it is desired to use the windlass for any purpose, such as grubbing stumps, haul- "ing, etc., or for pulling the machine itself out of difficulties the clutch member 425 is thrown intoengagement with its cooperating membenand upon the starting of'the motor'the windlass will be operated to wind its cable. The starting of the windlass, on account of the friction clutch mechanism 12, will be gradual and slow and by manipulat'. ing the handvlever 13 the speed at which the windlass is operated can be varied by varying the pressure between the friction nimbers of the clutch.

The attachment of the windlass to a tractor or similar vehicle is simple and convenienty and can be ldone without altering the usual construction. The location of the windlass at the front below the same is such as to relieve excessive strains from the frame andk preserve the fulltractive eliciency ofthe tractor.

A Various changes in the construction and ASSIGNOR TO THE HOLT MANUFACTUR` A spring-pressed dog` of the main frame and `windlass carries at itsvend, adjacent to the shownv and described may be-employed with.

out ydeparting from thev spirit of my invention as. disclosed in the appended claim.

'Having thus described my invention, what I claim and desire to secure by Letters Patent is;-

In aV tractor, ay Windlass detachably connected to the front end of the vmain frame below the same,l driving connections for said Windlass extending to the motor and inc'luding a transverse shaft journaled on the In testimony whereof I have hereunto set my hand 1n the presence of two subscribing witnesses.
